Introduction There are many different kinds of languages. You know English. You may have heard people speak other languages, such as Spanish, French, Korean or Italian. There is another language used to communicate that is not orally spoken. Sign language uses gestures and hand symbols.

Introduction When you use symbols or formulas in mathematics or science class, you are using still another form of communication. These symbols and formulas describe, generalize and communicate technological ideas.

Introduction Lines of varying style and thickness are used in specific ways to develop and communicate graphic messages about an object’s geometry. Imagine if all the lines had the same style, thickness, weight, and consistency. Understanding line types and when to use them will help your sketches look cleaner and more professional.

In your Notebook: How is sketching like a language? What do different types of lines tell us?

In your Notebook: 3. What is the purpose of sketching? 4. What are some common uses of sketching? 5.What are the advantages of sketching?

Purposes of Sketching Think through a design Convey your ideas Sketching Techniques Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Purposes of Sketching Think through a design Convey your ideas Uses lines and symbols to describe a design There are several purposes for creating sketches. Sketches help you to think through a design. They also help you convey your ideas to other people for better understanding. Sketching is a language just like any other. The difference is that in sketching we use lines and symbols to describe the shape, size, and even the function of a design.

Common Uses of Sketching Sketching Techniques Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Common Uses of Sketching Brainstorm Communicate Document Measurements In the engineering field, sketches are often used to brainstorm ideas and to solve problems. Many times they are used to communicate ideas to other people for better understanding or explanation of an object. Sketches are also used to document measurements taken in the field to be used back at the office.

Advantages of Sketching Sketching Techniques Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Advantages of Sketching Convenient Inexpensive Creating and using sketches provides several advantages. Sketches are convenient and can be created almost anywhere, plus they are inexpensive. Few additional materials are needed. Only pencil and paper is required to create a sketch.
